When an antigravity account returns 500 "Internal error encountered." on all 3 retry attempts, increment a Redis counter and apply escalating penalties: - 1st round: temp unschedulable 10 minutes - 2nd round: temp unschedulable 10 hours - 3rd round: permanently mark as error Counter resets on any successful response (< 400).
